IMPROVEMENT IN SEAL-Locks.

Therschedule referred to in these Letters Patent and niaking part of the sameA We, JOSEPH OonBE'rT, of Brooklyn, and FRANK- LIN W. BROOKS, of New York City, both iu the State of New York, have invented a new and improved Device for Sealing Locks and other Fastenings, which is `described as follows:

Nata-re and Objects of thc-Invention..

Our invention consists of a sliding case containing -without breaking said seal.

. Descr/@tion of the Accompanying Drawing. Figure 1 is a perspective view of the face of a lock,-

the seal-cover being raised and the seal Withdrawn from the key-hole.

-Figure 2 is a rear view of the same-faceplate.

Figure 3 is a vertical section on the line x y, iig. 2.

General Description.

A is the face-plate of a/padloek, showing the holes, er, for rivets, by which it is secured to the body of the lock.

B-B are two recessed iianges on the face of the plate A, forming an escutcheon round the key-hole C.

D is a sliding plate having beads on its upper and lower edges', the middle portions heilig occupied by the glass plate E, whose rear has a rariegated pattern. This glass is introduced into the slide-plate when the latter is in its lowest position, as shown in tig. 1, a portion of one of the flanges B being cutaway to allow the glass to be slipped into its place in the slide-plate. l

F is a hinged cover, which shuts down over the slide-plate and glass to protect the latter.

yGr is a pin, which projects through the plate A and enters a hole in the slide-plate D when the latter is in\ closed position, as shown in g. 3.

E is a spring, which forces the pin through the plate, except when it is forcibly retracted by pressure on the end ofthe pin. I

When the lock is fastened andthe plate D in its closed position, (lig. 3,) it is necessary to break the glass platel before the end of the pin G is exposed. lhe glass being broken, a pointed tool or pin on the end of the key is pushed against the pin, so that the slide-plate D may be free to move and the key-hole be uncovered. This being done, the key is introduced and the lock opened in the vusual manner.

rlhis device is intended lfor seal-locks for revenue purposes, for safes, boxes, packages, 8vo., in store, bank, safe-companyvaults, in bond, in care of express or other transportation companies, and in other vplaces where it may become an object with the government, the proprietor, the shipper, or the custodian to determine that no access shall be had without the presence of the proper person with whom rests the responsibility of breaking the seal and opening the lock.

We have shown the device as applied to a padlock,

but there are other descriptions of locks and different fastenings towhich it may be adapted.

'lhe plate upon which the slide is founded' may be *I placed around a screw-hole, so that the plate shall cover lthe head of a screw, and thus preventr access' thereto without the breaking of the glass. The screw thus protected may secure-the lid of a packing-case or any description of box, or it may fasten' the lid of a con.

. The same description of plate with a glass seal may be made to form a part of a clutch-box or clasp which unites the ends of a cord or strap around a package of any kind.`

Many other applications will occur to the expert,

and will growout ofthe use ofthe invention.

The variegations in the glass seals may be-produced in the course of their manufacture, `or subse-VV 'retracted while the seal is in positionwithout breaking the latter.
